What do you think?

Demote domain controller in 2008 Active Directory.

OS - Windows 2008 R2
AD - 2008
DC - GC, Second DC in the forest.

How to demote a DC in 2008 AD?

Go to Start --> Run --> Enter "dcpromo". This will start the installation wizard.

Select "Next"

In the next screen its asking if this is the last dc in the domain. In my case I need to just demote the existing backup dc for hardware refresh. Moving it to a new server...I did not select the option.

If you chose to remove the AD integrated DNS zones select the "Delete" option as shown.

This will prompt you for the Admin id/password as shown below

The wizard will present you the summery and off you go demoting your DC.
